The diagrams below show the design for a wave-energy machine and its location. OL8d
The two diagrams provide information about the functioning of a wave-energy machine as well as informs us about the location options for the installation of the device according to the length of the waves and the cost of it with the volume of output, it will generate. Air travels upwards into the lower chambers of the machine with the help of water waves which causes the lower turbine to spin. At the same time the upward set of turbine is rotated by the airflow in the atmosphere. This generates electricity using the speed of the turbines caused by different airflow. When the equipment is installed in deeper sea-level, it yields higher output and requires high installation cost, while those build nearer to the ground generates low output and needs lower installation cost. Overall, it can be seen that the volume of electricity generated depends on the wave length of water as well as the airflow. The location of installation, however, creates a difference in administrative costs and output level.
